So I am about to install my aftermarket intake manifold and I would REALLY like to delete the passenger rear pcv..
doing that, will that effect the drivers side ? Because I have a catchcan n stuff already on that side and id like to have some valvecover venting.
Will I get a cel if I cap off that pcv at my valvecover? I have an aluminum valvecover so it is easy to cap that off. Not a big deal as I can have it tuned off but any drivability issues ??
If i do cap off this pcv , are there any negative effects such as excessive crankcase pressure or anything???
I add a pic of my engine and the manifold I'm going to use to give you an idea..
Any tips or advice is always much appreciated..

If you block both sides you won’t see a CEL. I would catch stuff on driver side, but it was mainly from letting the car warm up or not driving in boost. Winter time I would collect more versus summer time. It would be a gas, water, oil mix. I didn’t see a difference in how the car ran at all. There aren’t many people on here that block it off, hell I think I might have been one of the only ones for the 3 years I had the n14. The plugs are cheap enough that if you don’t like the way it runs then you aren’t out that much at all, like a tank of gas. If I had to do it again, I’d probably just catch can both sides.

thing is , it wont he as simple as putting the hose back on. I'm going to running an aftermarket manifold so either i plan for pcv or i dont but i need to decide because once I pick one , I gotta run it that way or remove my manifold and set it up again. And I'd rather just do this once , I'm already having to do a clutch job 2x all because of a bunk 50$ throwout bearing on a 1500$ job 🤬
UNFORTUNATELY dual catchcan just won't work either on my setup as I have no room to mount or plumb in that 2nd can without boomeraboogering up stuff to make room and routing of the lines , I actually have a 2x extra catchcans lol from trying to plumb them in ( I got 2x different styles to try different routing )..
so I shouldn't get a cel from blocking off just the passenger side ? I actually have the plug already to block it off and I couldn't find an adapter to fit the big pcv line BUT I could always run a reducer into it to do so BUT I'd rather delete that side and keep MOST oily air from entering my manifold and then my valves..
you are correct about the drivers side not catching much more than condensation, after 400x miles i had water vapor and the tiniest bit of oil mixed with it, which was kind of surprising because lolol my buddies catchcan after 400x miles somehow is over 1/4 full ( I think from all his short drives and constant engine idling)..
I found a great , cheap pcv plug.. BAR STOOL ANTI-SCUFF cap ! It fit perfectly once heated up a little bit and stretched over and sealed tight once cooled. Doesn't get warm enough either to come loose.
I also don't seem to be having ANY negative effects after deleting the pcv. I DID install an aftermarket manifold so i cant say how it effects drivability but i can say i have gotten NO problems like odd idle , loss of power , smoke from exhaust or cel...
I'd highly suggest doing this before your valves get too bad.
Okkkkkkkay........Looks good is that still in the mockup stage........I see some hose clamps still missing........Have you attempted to
try to start it yet.....
Runs LIKE A MONSTER !!! EXP after retune and added a few more psi.. whooo weeeee ! It also added a nice loud POP between shifts..
this manifold is all is made out to be.. definitely definitely all around gains !!!!
I also got NO drivability issues from the rear pcv delete..
